To me, e seems more natural
Agreed. I'm a great exponent of eating πie off a log table made from the branches of trees with square roots (although some think this is rather radical, I think it's an integral part of the experience; it's what differentiates the true mathematician from the remainder)
I though a slice of pie, rather then the entire pie, with only two scoops of ice cream was the diet.
Oh yer, good point. (As he heads back to the frezzer for the rest of the tub)

Mike,
You have a Pi-snack - and here is the Pi-drinking.
The price of vodka in Soviet times long time was:
0.25 liters - 1 ruble 49 kopecks and 0.5 liters - 2 rubles 87 kopecks.
1.49^2.87=3.14

I'd like to remember Pi Day by making reference to one of your previous posts, Valery. (I could not think of a good reply to your remarks about Laplace transforms, so I did not post there.)
A circular slide rule is compact precisely because it wraps a linear slide rule around the circumference of a circle. The key to the transformation is pi.
Here is a snapshot of my own circular slide rule, a Sama and Etani "Model 90" (the diameter is 90 mm). Note that the "1" indicator on the C scale is lined up with pi on the D scale. So slide (rotate) the red indicator around to 9 on the C scale (for 90 mm) and read off 2.83 (i.e., 283 mm) from the D scale. Therefore, pi times the diameter 90mm is the circumference 283 mm.
Since there are 25.4 mm to an inch, we get 283/25.4 = 11.1 inches. To do this division on the circular rule, rotate the C scale until 2.54 is beneath 2.83 on the D scale. Then the C scale's "1" indicator points to 1.11 (11.1 inches) on the D scale. So our circular slide rule is equivalent to an 11-inch straight rule, at least for multiplication and division, since they use scales near the circumference of the rule.
Pi rules!
